I can't answer your specific questions, but here's some useful information on V-belts;

calculating belt length if pulleys are equal diameter
L=2C + 3.14D
where L = belt length
C = centre distance between pulleys
D = pulley diameter
3.14 = pi rounded to two decimals

calculating belt length with unequal size pulleys (approximate)
L=2C + 3.14(D/2 + d/2)
where L = belt length
C = center distance between pulleys
D = large pulley diameter
d = small pulley diameter
3.14 = pi

This should get you very close to the belt length.

As far as widths, V-belts come in standard and high capacity sizes;

Standard V-belts come in 5 cross sections;

A 1/2" wide, 5/16" deep
B 21/32" wide, 7/16 deep
C 7/8 wide, 17/32 deep
D 1 1/4 wide, 3/4 deep
E 1 1/2 wide, 29/32 deep

High capacity V-belts come in 3 sizes;

3V 3/8 wide
5V 5/8 wide
8V 1 wide

Your NAPA store should be able to lend you a pulley groove gage to determine the size and shape of the pulley. Hope this helps. Bill.
